Definitions

  • a furnace for partial heat treatment of tools which has a working area and a clamping area.
  • the clamping area of the tools is fastened in a holder, which is insulated and / or cooled during the heat treatment, so that only the working area is heated above the material-specific transition temperature and then quenched, while the clamping area is at an essentially the same temperature level during the heating. and quenching treatment remains.
  • the tools with their clamping area are inserted into holes in the plate-shaped holder, which is insulated and cooled against the furnace chamber.
  • brackets are integrated in a plate made of heat-insulating material, which divides the useful space of the furnace into two separate heating rooms, and that the connecting links between the heating elements are designed to be movable.
